This invention relates" to improvements in yarn cleaning andknotcatching devices;

In carrying outrn'yinventioii I employ a su ortin member or bracket andtwo bars comprising base portion-s secured to the'supporting member,andparallel extensions projectingfromthe base portions and forming ayarn passagebetween then An object ofthe'invention'is to provide adevice of novel construction which can be manufactured at low cost;which may be quickly adjusted to" take care of dilferent counts ofyarn;-and which will be strong and rigid and retainits adjustment when inserv1ce.-

Another objectofthe invention is to provide 'adevice in which each barmay be readily invented to present a*new'- surface to the yarn passagefor-wearingpurposes,

WVith the foregoin and related'object's in view the invention consistsof-the elements andthecombinations of them hereinafter' describedand-clain'ied, y e

In the accompanying drawings illustrating the invention: s A

Figure 1 is a rs'peetiv -viewof a yarn cleaningand knot catching deviceembodying my invention.

Figure 'Q-is a sideview of the device;

Figure 3 is a topview thereof.

Figure is a front view-'the1'eof,'.and

Figure 5 is an end View'of'onefof" the bars which formsaparti of theyarn passage.

Referring to the drawings, my iniprovcd device as herein illustratedcomprises a supporting member or bracket 2',- upper and lowerpar'allelbars-3 and-screws 5 forsecu ing the bars to themeniber 2.

The supportingmember orbracket 2 may be of any shape and size for its'inten'ded'purpose. As herein 'jillust'rated, it comprises ashank-portion 6"having'a head 7 forined on one'end thereof. Theshankportion 6 is provid'e'd with a slot'8'; for the reception of a screw bymeans of whichfthe member or bracket may be secured-to" a machinerequiring the device when it is placed in service thereon.

The bars 3 are arranged in parallel relation and each bar comprises-abase'portion 9 and qa xte'nsion '10. projecting therefrom.

Each bar 3 as herein'illustrated', is formed from' a, bar originallysquare inci'osis section throughout its'lengt-h and fromwhich-diago'nally opposite corner portions are "cut'tfo form theextensionltl, leaving the base portions"9"square or rectangular incrossfsection. This. cutting away of-the diagonally-opposite cornerportions of the-"original bars or blanks provides extensions 10 each ofwhich has a Width greater than its thickness and each of which extendsbetween diagonally opposite cornersof its base portion 9,as clearlyshown in Fig. 2. V

The yarn passage jl l is-for nield between the v extensions 10,"andthe'yarnisdrawn through the passage 11 in"thedirection-"ofthe arrow, inFig. 2 when the device is; in service. The extensions lOare formed withrelation to their bases -9 so that'they' diverge forwardly front-theregion "of the entrance to the yarn passage ll asseen in Fig. 2; Thisconstruction' provides opposing surfaces for th"e extensions 10 forcleanlng the accumulation of lint or dirt therefrom.

The extensions 10 are forniedwith-opposite convex surfaces'as shown inthe-drawings; and, informing each extension 10 from theoriginal squarebar, the flat'sfides oi the bar are not cut away betweenthe"corners 12thereof and th'e'lines 135 as shown i i-Fig, 5,

soth at when the two barsfiare flated -to each other, as shown in thedrawings,tlie yarn passage 11' will 'be formed between flat parallelsurfaces for a short distance'from the entrance thereto,' andjso thatthe rearward surfaces of the extensions 10 will extend sub stantially inthesaine p'lane'at right angles to the direction of travel oflth'e yarnfor a short distance fro ntheentrance, ofthe yarn passage 11 and therebypresent obstruction walls to a knot or slub on the yarnpass'ing grooves16 on either side of either bar may be applied to the ribs 15 for thepurpose of turning or inverting either bar. When either bar 3 is thusturned or inverted its extension 5 will occupy exactly the same relationto the extension 10 of the other bar as it did before it was invertedexcepting for the re- 7 versal of its parts. Thus each bar 3 may bereadily inverted to present a new wearing to surface for the yarnpassage11. Y

The base portion 9 of each bar is provided with an opening or hole 4therein through which one of the screws. 5 extends to secure the baseportion to the supporting member 2, the screw 5 being screwed into thehead 7 of the member 2. The diameter of the hole 4 is greater than thediameterof the body of the screw 5 extending therethrough to permit thebars 3 to be adjusted toward and from V '20 each other when the screws 5areloosened.

This adjustment is provided to vary thespace between the extensions 10thus vary the yarn passage 11 to accommodate different counts of yarn,The engagement of the walls of the grooves 16 with the ribs 15 preservesthe parallel relationship between the bars 8 both during the adjustmentsthereof either toward or from each other and after the bars have beenadjusted, they may be secured in their position of adjustment bylthetightening of one or both of the screws 5. V v

lVhen it is desired to invert either bar 3 to presentanew wearingsurface to the yarn passage 11 it is merely necessary to remove it andits securing screws 5, fromthe supporting member 2, give the bar 3 ahalf turn onits longitudinal axis, re-engage it with the member 52 andinsert its screw 5 to secure itin its inverted position. i

I claim as my invention:

1. The combination ofa supporting memher, and twobars comprising baseportions secured to the member, and parallel extensions forming a yarnpassage between them, each bar being invertible, the member and the barshaving opposing surfaces which engage each other and position the barsrela tively to each other 'andprevent them from turning, and theopposing surfaces of the extensions diverging forwardly from the regionof the entrance to the position of each bar. a

2. The combination of a. supporting memher, and two bars comprisingbaseportions secured to the member, and parallel extensions forming a yarnpassage between them and forming corners at the entrance to-the yarnpassage, the opposing surfaces of the extensions diverging forwardlyfrom the region of'the entrance to the yarn passage, and

the rearward surfaces of the extensions extending substantially inthesame plane for a short distance from the corners at the en trance to theyarn passage. i i

3. The combination of a supporting mefmof each bar.

- 4. The combination of a supporting'member having aguldmg Ilb, two barscomprising base portions arranged one above the other and parallelextensions forming a yarn passage between them, each bar beinglnvertlble, andeach base portion having parallel grooves in oppositesides thereof either of which may receive therib, and means, to secureeach bar to the member vwith either groove ofeach bar fitted to the rib.

5. The'combination of a supporting member having a, guiding rib, twobars comprising base portions arranged one above the other and parallelextensions forming a yarn passage between them, each bar being in-.vertible, and each base portion having parallel grooves in oppositesides thereof either of which may receive the rib, means to secure eachbar to the member with either groove of each bar fitted to the rib, andthe. 1

opposing surfaces of the extensions diverging forwardly from the regionof the entrance to the passage in each position of each bar.

6. The combination of a supportingmemher having a guiding'rib, two barscomprising base portions arranged one above the other and parallelextensions forming a yarn passage between them, each bar beinginvertible, and each base portion having parallel grooves in oppositesides thereof either of which may receive the rib, means to'secure eachbar to the member with either groove of each bar fitted to the rib, theopposing surfaces-of the extensions diverging forwardly from the regionof the entrance to the passage in each position of each bar, and thepassage in each rearward surfaces of the extensions extendingsubstantially in the same plane for a short distance from the entranceto the yarn passage in each position of each bar.

7. The combination of a supporting member, and two bars comprising baseportions secured to the member, and parallel extensions forming a yarnpassage between them, each bar being invertible, each base portion beingrectangular in cross section, and each extension having a widthgreaterthan its thickness and extending between diagonally opposite corners ofits base portion.

7 8. A bar for a yarn cleaner and knot catcher, comprising a baseportmmrectangular 1n llli) cross section, and an integral extensionhaving a Width greater than its thickness and extending betweendiagonally opposite corners of the base portion.

9. A bar for a yarn cleaner and knot catcher, comprising a base portion,rectangular in cross section, and an integral extension havhaving ing awidth greater than its thickness and extending between diagonallyopposite corners of the base portion, the base portion 10 parallelgrooves in opposite sides thereof.
